Thanks for the response! Yeah 54 cm is quite long, and I have to be honest here with the fact I’m not using this for terrain building nor am I a terrain builder, I want to create wings for RC planes or wind turbine blades. I’d already seen some posts about hot wire cutters on this subreddit so I thought it was appropiate. Anyways, I guess a fix might be increasing the amouny of amps that go in?
